Hi 2 days ago my transmission starting slipping between 2nd and 3rd gear, and then between 1st and 2nd gear but less often. my fluids are good and I had my tranny flushed in December. The car is just shy of 180k miles. I brought it to a tranny shop to get a consultation as they told me that the problem may not be the transmission. Today they told me that the codes they are getting are for a bad ELD as the voltage was off and that may be causing the transmission to not work properly. They are telling me that is where I have to start. They said there are no aftermarket ELDs for that car and they would have to get it from Honda. With parts and labor that would be $1,300. That doesn't sound right to me and something sounds fishy. Any ideas, concerns, suggestions?

Car make/model?
Auto (assumed) or manual trans?

If you've an auto and had old dirty fluid in it prior to the flush, that old dirty fluid may have been the only thing providing grip for your worn clutch packs. Or, the flush could have caused particles to plug an orifice.

I've no idea how an ELD (electric load detector) would affect transmission shifting in an auto. In fact, I don't think it would. Here's a quote I found on another site. "The ELD is simply an energy saving device. It measures electrical load and sends the information to the ECU, which turns off charging by the alternator when electrical load is low to increase gas mileage. It is not involved in idle control. The ELD is integrated into the under hood fuse box. "

Looking at FSM wiring diagrams, it's an induction loop. Basically, it converts the magnetic field surrounding a battery wire into a current that the ECU uses to compare load demands. From looking at the FSM diagram, the only way I could imaging it could go bad is if it physically corroded or broke. However, the ECU circuit that interprets the current fluctuations could be bad. Maybe a lifted contact around the resistors. I'm assuming it uses relays but don't know. There might be a capacitor in the circuit.

All that being said, people have had the engine bay fuse box go bad on them.

PS. Now that I made assumptions. Someone will jump in to correct me. People don't answer questions around here. They just correct others.

Make/Model/Trim and modifications is required information if you hope to receive accurate feedback.

Many times an ELD code is a false alarm. Clear it and see if it comes back.

The pre 1996 automatics are mechanically controlled through the first 3 gears, there is no way an electrical issue could cause a problem.

"Slipping" in the transmission makes the engine rev up a lot without the car going proportionally faster. Is that what is happening?
